  • Canon 7d, t5i, 80d, 6d, t1i, rebel t5, t3, 500d, 5d mark iii...

The "memory card cannot be accessed" error would prevent you from taking photos or viewing files. As the full error message implies, [1] try to reinsert the card for a couple of times, [2] change the card with a new one, or [3] format the SD card in the camera. Those manners are meant to make the card function well.

Before taking action to troubleshoot with suggestions, you must find a digital camera recovery solution first. Data recovery is prior to SD card repair, as long as you cannot afford to lose the media files in the malfunctioning storage card.

Quick Tip: If it's a brand new memory card that you use it for the first time, make sure that you format the SD card to FAT file system, which digital cameras can recognize it properly.

2. Why cannot I recover 2GB data for free?

It is recommended to check the version installed is Free or Trial because they are different versions.

Trial has data preview function but cannot save any files, while the Free version enables to recover 2 GB files. The default free space is 500 MB and you may share the product on social media to get another 1.5 GB.

3. Why cannot the recovered files be opened?

A file is saved as 2 parts on the storage device: directory info (which is comprised by file name, time stamp and size info, etc.) and data content.

If the files with original file names and folder structures cannot be opened, one possible reason is the corrupted directory info. There is still a chance to recover the data content with the RAW Recovery method in our software.

4. Why isn't it suggested to recover the files back to the original drive?

The storage structure of the lost files would be altered or damaged by any changes on the drive. If you save the recovered files back to the same drive, the original data structures and data content would be corrupted or overwritten, which causes permanent data loss. So you should prepare another disk to save the files.

5. How can I check whether my data is recoverable or not before purchase?
